The present invention provides a cosmetic composition that provides a coat to hair with improved persistence to repeated washing. Complementary chemical functional groups derived from groups A and B in a cosmetic composition containing polymer PA and polymer PB bearing chemical functional groups derived from non-photoactivatable groups A and B, respectively. A chemical functional group, so that the polymer PA and PB do not form a covalent bond before being applied to the keratin material, but can be formed after the application, and the chemical function group of the group A is changed to epoxide, aziridine, etc. And the chemical functional group of the group B is selected from the functional group XH n where X = 1, 2 or 2 with X═O, N, S, COO.
